Description

The The invention relates to a floor spring with a housing for receiving a locking mechanism the case in the area of a a door or the like supporting Schließerachse of a cover member is covered.

Such Floor door closers are well known. They have a housing which is surrounded by a cement box, which is in an im Floor recessed recess is used. Going up the entire cement box with the bottom door closer of Covered a cover plate, so that from the outside only this cover plate too see is. Since the cover plate only after mounting a door or the like at the bottom door closer and also only after z. B. the closing speed has been set on the bottom door closer is, can be mounted, the cover plate must be on one end face one in the longitudinal direction have extending slot so that the cover plate on the closer axle past the housing mounted the floor spring can be.

The Cover plate can either be on the cement box or on the housing of the Floor door closer fastened be. Since it is necessary that the housing of the floor spring in the Cement box can be adjusted in all four directions in the plane and in connection with the above-mentioned various attachment options The cover plate on the cement box or on the housing are different size slots in the cover plate.

An inventive cover component consists of a base 1 and a mission 2 , The basic part 1 is in different views in the 1 to 8th shown during use 2 in the 9 to 13 shown in different views.

The following is the basic part 1 described. The basic part 1 is for example by injection molding of plastic, z. POM. It is designed as a substantially flat plate with an elongate recess open on one side, so that a substantially U-shaped form results in the plan view. At the inner edges of the recess is the base part 1 each with concave semi-circular and extending in the longitudinal direction of the recess recesses 3 Mistake. The end face of the recess is of a semi-circular in plan view contour 4 completed. The contour 4 is with an inwardly directed sealing lip 5 provided, which is directed obliquely upward (see. 5 ). The sealing lip 5 , which may be formed in profile as a radial shaft seal, engages in a groove, not shown, a closer axle 10 the bottom door closer and thus prevents the ingress of dirt. At the inner edges of the recess in the base 1 are in the rear area on each side each a detent 8th intended. In addition, on the inner edges of the recess Einführfasen 11 arranged, showing the joining of basic part 1 and use 2 facilitate. For length adjustment of the basic part 1 to the respective conditions is the basic part 1 at its free ends with predetermined breaking points 16 provided, which is a simple reduction of the legs of the base 1 enable.

In the 9 to 13 is the one in the main part 1 retractable insert 2 shown. It is like the basic part 1 from a plastic injection molding part, z. B. POM, and has a substantially rectangular shape with a semicircular contour 4a on a narrow side. At its outer edges is the insert 2 with outwardly projecting wings 6 provided, which with the wells 3 at the inner edges of the base 1 can be brought into engagement. The wings 6 have a contour such that they are in the wells 3 fit. Through the interaction of the depressions 3 at the base 1 and the wing 6 on the insert 2 So a good fixation of the two parts can be achieved. The semicircular contour 4a on the narrow side of the insert 2 forms a sealing lip 5a and corresponds in shape to the contour 4 the sealing lip 5 at the base 1 , In the area of the wings 6 is in one end of the insert 1 a recess 7 provided for latching between the base 1 and the mission 2 with the locking lugs 8th at the base 1 can be brought into engagement and thus prevent mutual displacement of the two parts. Besides, are on the insert 2 Predetermined breaking points 16a provided to - as with the basic part 1 - To allow a length adjustment to the local conditions.

In the 14 and 15 is that from basic part 1 and use 2 existing cover component shown in the assembled state. The wells 3 at the base 1 are with the wings 6 on the job 2 engaged and the semi-circular contours 4 and 4a leave an area for the passage of the closer axis 10 free. Out 15 is also recognizable that the use 2 a lower height than the base 1 has, so that there is a height difference h, whose meaning below in connection with the 17 to 20 will be explained.

16 shows a plan view of the fully assembled floor spring, with the door has been omitted for clarity. The - not visible - floor spring is with a cover plate 12 covered and extends with its closing axis 10 through that from the base 1 and use 2 existing cover component. The use 2 the cover component is with a screw 9 attached to the housing of the bottom door closer and clamps due to the above-mentioned height difference h between the base 1 and the mission 2 the entire cover component firmly.

In connection with the 17 to 20 Now, the installation of the cover member will be explained. When the cover member is attached, there is a normally open case 15 of the floor-mounted door closer in a cement box 14 fixed in the ground and aligned.

First, the use 2 , as in 17 shown, for. B. obliquely from the top right, to the closer axis 10 pushed and then pivoted in a circular arc to the left, as indicated by the arrow in 17 is specified until the use 2 parallel to the closer housing 15 is aligned. Subsequently, the use 2 with the screw 9 on the closer housing 15 prefixed. This is the screw 9 not yet firmly tightened, ie the use 2 can still be moved and moved in height. Now the basic part 1 on the insert 2 deferred, with the wells 3 with the wings 6 engage. At the end of the insertion movement locking latches snap 8th at the base 1 in recesses 7 on the job 2 and fix so basic part 1 and use 2 to a unity. After locking the base 1 on the insert 2 will the screw 9 tightened and thus the basic part 1 about the use 2 clamped. A defined clamping of the cover member is due to the height difference h between the base 1 and the mission 2 achieved. Because the use 2 a lower height than the base 1 is, when tightening the screw 9 the use 2 pressed down and thus simultaneously clamps the base 1 firmly. After tightening the screw 9 becomes the cover plate 12 pushed under the cover and with fixing screws 13 at the cement box 14 or on the closer housing 15 attached.

As can be seen from the above description, a trouble-free installation is possible even with already inserted door. Likewise, the universal application of the cover component according to the invention both in plug-in axles and in rigid axles and in an attachment of the cover plate 12 at the cement box 14 or on the closer housing 15 given.
